GSP Collections

The Ruth Bitting Hamm Digital Library

Explore the collections housed in the Ruth Bitting Hamm Digital Library, named to honor a family historian and benefactor of several genealogical and historical organizations nationwide.

Search over 200 collections in the Member Collections and Public Collections and Resources. We also have several manuscript collections and other collections that are not yet listed online. The GSP Library Catalog has over 1200 books held by the library of The Genealogical Society of Pennsylvania.

The GSP digital newsletter, the Pennsylvania Genealogical Magazine (1948-2015), the Publications of the Genealogical Society of Pennsylvania (1895-1947), and the former GSP newsletter, Penn In Hand, are online for GSP members through the Publications page. A few remaining volumes of PGM need to be added to the website.
